And this probably is the cause of the stalls reported by many people on the list.

No, the real fix for the stalls will be in 2.1.122, the linearincrease case of congestion window calculations was completely wrongdue to a change I made circa 2.1.92 which is reverted now in 2.1.122

Setting the initial mdev to m<<1 is a bug in the BSD code which wejust copied blindly in 2.0.x, the calculation in 2.1.x (m<<2) is thecorrect one, check the RFCs :-). I believe this is mentioned inSteven's books and the tcp-impl "known TCP implementation problems"draft, amongst other places.
